[GLSA-200603-10] Cube: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200603-10
(Cube: Multiple vulnerabilities)

Luigi Auriemma reported that Cube is vulnerable to a buffer
overflow in the sgetstr() function (CVE-2006-1100) and that the
sgetstr() and getint() functions fail to verify the length of the
supplied argument, possibly leading to the access of invalid memory
regions (CVE-2006-1101). Furthermore, he discovered that a client
crashes when asked to load specially crafted mapnames (CVE-2006-1102).

Impact

A remote attacker could exploit the buffer overflow to execute
arbitrary code with the rights of the user running cube. A possible hacker
could also exploit the other vulnerabilities to crash a Cube client or
server, resulting in a Denial of Service.

Workaround

Play solo games or restrict your multiplayer games to trusted
parties.

Solution:
Upstream stated that there will be no fixed version of Cube, thus
the Gentoo Security Team decided to hardmask Cube for security reasons.
All Cube users are encouraged to uninstall Cube:
# emerge --ask --unmerge games-fps/cube
